How to visualize CUDA simulations? What are all the options?

I am currently writing a simulation in CUDA and I am looking for ways to visualize my data efficiently.

I have read you can use OpenGL + CUDA to achieve this. My question is what is your experience with this “interop” implementation. Does it have a high learning curve, is it easy to develop? Is there an existing framework/program that can be used to develop my graphical program?

Does a program exists which you can easily customize to your simulation: add buttons, sliders to adjust simulation parameters and so on?

Im not sure if it is what you are searching for, but i used “paraview” some time ago to visualize CUDA computations based on CFD code…

Paraview is well documented and ez to learn.
